[erek]

As of the Catalst 10.9 (AHCI drivers,) AMD now officially supports TRIM,

Does that add trim for the SB750 also?

Im still using the ms driver because intel ssd toolbox wouldnt work with the amd drivers iirc.

intel ssd toolbox doesnt work for me with the trim supported drivers

also... it might support trim for sb750

Thanks for the heads up erek

But if TRIM is working ok we shoudln't need to run that intel toolbox utility then right?

What does it do for performance?
thanks
On my Q6600/Intel platform I used to get 260MB/s read speeds. Since moving to SB850 - I get about 240-250MB/s.

I have 5.9 points on Windows Experience Index using the SB850 controller in AHCI mode, and 7.5 using IDE. It feels faster, it loads faster... it is faster as IDE, even on benchmarks (330MB/s vs 300MB/s).

Windows IDE drivers support TRIM, apart from maybe some benchmarks, how faster can AMD drivers be? I didn't install them before because they didn't have TRIM.

IDE drivers don't support TRIM mate - AHCI is required for TRIM.
And I wouldn't use WEI to measure SSD performance - it sucks!

Use ASSD or CrystalMark

Screenies speak for themselves - slight improvement in performance using the AMD drivers. Still need to figure out if they actually support TRIM lol

Nope. AHCI is required for NCQ, not for TRIM. Microsoft AHCI and IDE drivers BOTH support TRIM.

I use HDTune and in IDE mode works faster than in AHCI mode, both using Microsoft drivers, because AMD AHCI driver didn't support TRIM. Now that it does, I guess I'll have to test it.
